What SD CARD should I buy?

If you want an SD Card for your camera - these are the ones I use and recommend. 

I'd strongly recommend not to buy any SD cards off ebay - I've heard about too many issues with counterfeit cards - often sold on by unwitting resellers. My inbox regularly gets messages from people who bought a £150 camera then cheaped out and bought a £3 memory card on ebay - Then when it doesn't worth they blame the camera! It doesn't make any sense. Good memory is cheaper than it's ever been - see the links above.

A lot of HD cameras will not work properly with cards larger than 32GB (cards over 32GB are usually SDXC rather than the SDHC standard used by 32GB cards. SDXC cards use the ex-FAT system rather than FAT32 - in short they are a different standard). - so don't just buy the biggest card you can afford - read the specs in the manual to see what it accepts.


RECOMMENDED CARDS (for action cams - see dashcams below)

CLASS 10 UHS-1 CARDS (For HD Cameras)


U3 CARD (For 4K cameras)




The SD card in a dashcam is re-written over, more frequently than in other types of cameras. Some manufacturers void their guarantee if an SD card was used in a dashcam. So, no surprise, there are special High Endurance SD cards made just for's some.


VERY IMPORTANT. These links take you to the product, however Amazon have three different ways of selling. There's Amazon Direct - This means that you are only dealing with Amazon themselves, then there's other sellers that use Amazon's facilities - these show as Fulfilled By Amazon and finally there's Market Place sellers that advertise on Amazon, but operate independently.  I strongly recommend that you only use the first...the Amazon Direct - Sold By Amazon option. Even if it appears that you are paying a couple of £/$ more it is more than likely you are comparing the price of a real item against the price of a fake.

To give you an idea of the extent of the fake goods problem. In a 2016 survey by Apple - 90% of the 'Apple' chargers sold through Amazon - using the other the two methods..which includes the "Fulfilled by Amazon" option -  were found to be counterfeit....90%!

This 1972 Panasonic RS296-US music machine plays with history

Imagine a device that can store twenty playlists containing songs of your choice that you access at the press of a button. A device that could play music for over thirty hours without repetition.

It really doesn’t require any imagination nowadays as most people already own a pocket sized gadget that can do just that, but what if you had to make this device using only the technology that was available in 1972.

If you did, it would probably look something like the fantastic machine in the video below. 

It's interesting to note that the 2.5 days of music that Panasonic quoted on their advert is roughly similar in play time to the 1000 songs in your pocket that the first 5GB Apple iPod boasted twenty four year later in 2001. However to play tape for 60 hours would require fragile 180min cassettes, so a more realistic play time using twenty 90 min cassettes would be half that.

The Antikythera Mechanism I mention at the beginning* is a 2000 year old computer that has been in a number of documentaries - someone has uploaded a BBC video about it here

You may have spotted two special cassettes in the video - a Back to the Future Replica "Edward Van Halen" tape and a Guardians of the Galaxy "Awesome Mix Tape Vol. 1" - both were provided by my good friend Hugo from Walkman Archive - you can find more info on his tapes here:
Back to The Future         Guardians of the Galaxy

I'm not dissing cats - I love cats, and have been the proud guardian to a number of was a reference to the fact that the majority of the internet that I don't make is made up of cats.

Wow what fantastic piece of equipment in a bygone era. I enjoyed this video and watching the mechanical machine do its work

Hi, Thanks for your review. Just got one myself. Could you advise on where to buy replacement parts for the unit ?

September 12, 2017 | Unregistered CommenterMbg

You've done well to find one. Mine didn't need any repairs and I wouldn't know how to go about finding any. If I were you I'd ask the chaps on the forums.

September 12, 2017 | Registered CommenterTechmoan

Ok, thanks. Will do. The unit wasn't used much and looks quite mint. But I guess at least the belts should be replaced after all those years.
